The band hasn't specified the venue, but Arcade Fire said Tuesday it will play a concert in Los Angeles at an outdoor location on Oct. 29, the same day its highly anticipated new album, "Reflektor," is due in stores.

The show is part of MTV and Intel's so-called Music Experiment; tickets are available in a contest that appears to require interested parties to "make Reflektor art out of your old CDs," according to the Music Experiment website. (One might also need to fork over some social-media information.)

Arcade Fire is ramping up activity ahead of "Reflektor," which follows the band's Grammy-winning 2010 album "The Suburbs" and was co-produced by the group with Markus Dravs and James Murphy.

Last month it performed in its Montreal hometown and on "Saturday Night Live," and this week the group is expected to play two shows in Brooklyn, N.Y. On Oct. 26 Arcade Fire will take part in Neil Young's annual Bridge School benefit concert at the Shoreline Amphitheatre in Mountain View; Crosby, Stills, Nash & Young, Queens of the Stone Age and Diana Krall are also on that bill.

Fans who saw the last show of U2’s North American tour Friday at Madison Square Garden in New York City had an incredible bit of luck. For one thing, Bill Clinton was in the house, but blessedly refrained from sitting in on saxophone.

Fans who showed up Wednesday night in New York to see U2 tribute band Unforgettable Fire got more than their money’s worth when members of the real U2 — guitarist the Edge and bassist Adam Clayton — joined the performance.

The free summer concerts at the Levitt Pavilion band shells have long offered an invigorating mix of touring and local acts to the L.A. area. Saturday’s show at the Levitt in Pasadena figures to be one of this season’s highlights with the grand-scale retro collective Vaud and the Villains.

U2 singer Bono and guitarist the Edge joined Yoko Ono and various dignitaries on Ellis Island on Wednesday for New York City's inaugural John Lennon Day. They were there to unveil artwork dedicated to the late Beatle.
